Flavonoids are considered one of the most diverse phenolic compounds possessing several valuable health benefits. The present study aimed at gathering all correlated reports, in which Sephadex® LH-20 (SLH) has been utilized as the final step to isolate or purify of flavonoid derivatives among all plant families. Overall, 189 flavonoids have been documented, while the majority were identified from the Asteraceae, Moraceae, and Poaceae families. Application of SLH has led to isolate 79 flavonols, 63 flavones, and 18 flavanones. Homoisoflavanoids, and proanthocyanidins have only been isolated from the Asparagaceae and Lauraceae families, respectively, while the Asteraceae was the richest in flavones possessing 22 derivatives. Six flavones, four flavonols, three homoisoflavonoids, one flavanone, a flavanol, and an isoflavanol have been isolated as the new secondary metabolites. This technique has been able to isolate quercetin from 19 plant species, along with its 31 derivatives. Pure methanol and in combination with water, chloroform, and dichloromethane have generally been used as eluents. This comprehensive review provides significant information regarding to remarkably use of SLH in isolation and purification of flavonoids from all the plant families; thus, it might be considered an appreciable guideline for further phytochemical investigation of these compounds.

Xylitol has been widely documented to have dental health benefits, such as reducing the risk for dental caries. Here we report on other health benefits that have been investigated for xylitol. In skin, xylitol has been reported to improve barrier function and suppress the growth of potential skin pathogens. As a non-digestible carbohydrate, xylitol enters the colon where it is fermented by members of the colonic microbiota; species of the genus Anaerostipes have been reported to ferment xylitol and produce butyrate. The most common Lactobacillus and Bifidobacterium species do not appear to be able to grow on xylitol. The non-digestible but fermentable nature of xylitol also contributes to a constipation relieving effect and improved bone mineral density. Xylitol also modulates the immune system, which, together with its antimicrobial activity contribute to a reduced respiratory tract infection, sinusitis, and otitis media risk. As a low caloric sweetener, xylitol may contribute to weight management. It has been suggested that xylitol also increases satiety, but these results are not convincing yet. The benefit of xylitol on metabolic health, in addition to the benefit of the mere replacement of sucrose, remains to be determined in humans. Additional health benefits of xylitol have thus been reported and indicate further opportunities but need to be confirmed in human studies.

Grapes (Vitis vinifera L.) are commonly known grape species that belong to the Vitis genus in the Vitaceae family and come from western Asia and southern Europe. This review consists of traditional uses, phytochemical compounds, nutritional constituents, pharmacological activities, genotoxicological studies, and toxicity studies of V. vinifera. The data were obtained from scientific databases and search engines such as PubMed, Elsevier, Springer, Frontiers, Google Scholar, Scopus, Science Direct, and MDPI. In some countries, grapes used for traditional uses, such as drug therapy for blood-forming, anemia, allergies, wound care, colds and flu, carminative, bronchitis, diarrhea, and anti-phlegm. The main phytochemical compounds in V. vinifera are phenolic compounds, aromatic acids, flavonoids, proanthocyanidins, and stilbenoids. Nutritional constituents can be found in grapevines, i.e., proteins, lipids, carbohydrates, minerals, and vitamins. Parts of the grapevines had a wide variety of biological activities, i.e., antioxidant, antiviral, antiplatelet, antifungal, anticataract, antiobesity, anticholinergic, anti-sunburn, anti-inflammatory, and wound-healing activities. The phytochemical compounds content in each part of the grapevines were different. Each pharmacological activity depends on the grapevine's phytochemical compounds, components used, and extraction type. However, more studies are needed regarding the genotoxicity and toxicity of V. vinifera.

Polyphenols are the most prominent natural antioxidants found numerously in nature. They are secondary metabolites recognized for having high health benefits for consumers, even if the exploitation of these remarkable natural compounds is still a challenge. Moreover, there is a dilemma over the nutritional value of polyphenols. Hence, this paper seeks to review the classification, sources, anti-browning effect, antioxidant activity, nutritional property and anti-disease effect of polyphenols for better understanding the issues which need to be addressed in the valorization of these natural compounds.

Traditional medicine provides an important health care service and can be used as an alternate therapy. Plants are rich in phytochemical compounds that offer a source of dietary ingredients used to treat various ailments and problems. Spearmint (Mentha spicata L.) belongs to the family Lamiaceae and is a rich source of polyphenols. These polyphenols have shown numerous biological activities and health benefits. Also, conserve biodiversity and manage soil-borne pests as well as enhance soil and plant health. Therefore, the review of the present study shows the bioactivity, health effects, and inter-cropping advantages of spearmint.
